Hi guys and girls, im pretty new to gardening and this may seam like the most silly question but i have a established fern garden that i put wood chips down as a mulch. All growing great guns ! I am wanting to put in some soil conditioning stuff like sheep poo or mushroom compost any tips on how to do that do i scrap back the wood chips or lay it on top and then put more mulch on top ??

I use both of what your asking about. I put the sheep poo down then the mushroom mulch and the chips on top. This will stop it from blowing away and retain the moisture good. But be warned you will more than likely be bomb barded with mushrooms as I do.

No do not put the mushroom compost and sheep poo over the top of the chips it will defeat the purpose of the exercise. I would remove the chips first. What type of wood chip do you use? and what plants are you putting the wood chip onto? reason I ask is some chips are not compatible with some plants like Eucalyptus and even pine bark can be bad if it is still green. If you are sure it is not going to kill your plants then use it but for me I'm a huge fan of either Pea straw or Lucerne both have a got amount of Nitrogen which is good for the soil and plants and will hold the moisture well.
